White Paper 9: Are SHA-1 Devices Still Secure Enough?

Abstract: In 2005, a group of Chinese researchers attacked the strength of the Secure Hash Algorithm (SHA-1). This white paper discusses that attack and shows that, although the algorithm is slightly less collision-resistant than previously thought, the security of the SHA-1 memory devices from Maxim is not affected. Thus, the company's SHA-1 memory devices (DS1963S, DS1961S, DS2460, DS28CN01, DS28E01-100 and DS2432), will continue to provide a low-cost, effective solution for accessory/peripheral authentication and tamper-proof, verifiable memory applications.
